Angular Momentum The angular momentum L of a particle at any instant about a point O, the origin of a coordinate frame, is defined to be (7-25)L=r×mv=r×P where r is the position vector of the particle, m is its mass, v is its velocity, and p is its linear momentum. Angular...

也就是说,当没有torque的时候, d\bar L/dt=0, angular momentum为常量。 Angular momentum of a system of particles The total angular momentum of a system of particles about some point is defined as the vectors sum of the angular momenta of the individual particles: \bar L=\sum \bar L_{i...
Thus, the angular momentum is in the direction of the thumb. Another way to do this is to curl the fingers around the axis of rotation in the direction of rotation and stick out the thumb. For a right hand, the counter-clockwise rotation will have the thumb point straight up, while ...
point chargearbitrary motionsolid-angle integralsWe calculate directly the rates of emission of energy and linear momentum by a point charge in arbitrary motion using mathematical results that render the calculation of solid-angle integrals very simple. We show that the results of these explicit ...
The relationships between angular impulse and angular momentum have been derived in the particular case of collisions between rigid bodies. It is shown that the change in absolute angular momentum about an arbitrary reference point is always equal to the angular impulse. However, the change in relat...
